Abstract
A 56 year-old man with a 2-year history of transitional-cell carcinoma of the urinary bladder presented with back pain and diffuse radiological osteosclerosis. Laboratory studies revealed borderline-low ionized serum calcium, and markedly elevated serum alkaline phosphatase (ALP) activity and serum osteocalcin. Serum acid phosphatase and prostatic-specific antigen (PSA) were normal. Serum 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D were just below the normal limit and parathyroid hormone was moderately elevated. A translilac bone biopsy specimen revealed expanded bone trabeculae, abundance of osteoidcovered surfaces, and heavy metastatic spread. To the best of our knowledge, this is the first description of the association of osteosclerosis and metastatic transitional-cell carcinoma of the bladder.
